Once upon a time, there was a magic hat that could make any wish come true. One day, a young girl put on the hat and wished for a rainbow castle of her own. Suddenly, a large castle with a brilliant rainbow roof appeared before her. The castle was guarded by a mighty dragon. The dragon was friendly and had the key to the castle, so the young girl was able to explore it. And, she lived happily ever after in her rainbow castle.
